PI3PCIE2215
3.3V, PCI Express® 1-lane,
2:1 Mux/DeMux Switch
Description
Pericom Semiconductor’s PI3PCIE2215 is a 4 to 2 differential chan-
nel multiplexer/demultiplexer switch. The PI3PCIE family of switch
solutions is fully compliant with PCIe® signals at 5.0Gbps. Due to
its low bit-to-bit skew, high channel-to-channel noise isolation and
high bandwidth, this product is ideal for PCI Express switching.
Application
Switch a PCI Express® lane output between two PCI Express lane
inputs
